BANDPASS FILTERS

Bandpass Filters are often one of the easiest ways to drastically improve image quality. They are designed with a Gaussian transmission curve to emulate the output of the most common types of LEDs used in machine vision and are great for testing the effects of monochromatic imaging. All Bandpass Filters have an anti-reflection coating to ensure maximum transmission.

LONGPASS FILTERS

Longpass Filters provide seamless transition from reflection to transmission and are available in many wavelengths, depending on the needs of your system. Longpass Filters are best used in a controlled environment when multiple wavelengths need to be passed and are an economical solution for blocking excitation light in fluorescent applications.
